i2c-tiny-usb - (c) 2006 by Till Harbaum --------------------------------------- http://www.harbaum.org/till/i2c_tiny_usb The firmware code itself is distributed under the GPL, but one of the usb codes comes under a separate license. Plase see the .txt files in usbdrv for details. The default configuration is for a attiny45. The Makefile.mega8 allows to compile the device for the Atmega8 cpu. This includes the possibility to use the atmega8 rs232 for debugging. The attiny45 has to be programmed in high voltage serial programming (hsvp) mode since this application needs the reset pin to be reconfigured for other use. This project supports two usb implementations: the avrusb and usbtiny. Due to this four Makefiles exist: Makefile-avrusb.tiny45 - build with avrusb for Attiny45 Makefile-avrusb.mega8 - build with avrusb for Atmega8 Makefile-usbtiny.tiny45 - build with usbtiny for Attiny45 Makefile-usbtiny.mega8 - build with usbtiny for Atmega8 Just type make -f Makefile.xxx program to compile and upload the file. Please adjust e.g. programmer settings in the Makefile. If you don't want to recompile the firmware yourself you might use the included main.hex which is a prebuilt binary for the attiny45. Plase make sure you adjust the fuses accordingly. They need to be set to "external crystal > 8Mhz" and the RESET pin has to be disabled in order to be re-used for application specific purposes. See Makefile-avrusb.tiny45 for more details.Download Driver Pack
After your driver has been downloaded, follow these simple steps to install it.
Expand the archive file (if the download file is in zip or rar format).
If the expanded file has an .exe extension, double click it and follow the installation instructions.
Otherwise, open Device Manager by right-clicking the Start menu and selecting Device Manager.
Find the device and model you want to update in the device list.
Double-click on it to open the Properties dialog box.
From the Properties dialog box, select the Driver tab.
Click the Update Driver button, then follow the instructions.
Very important: You must reboot your system to ensure that any driver updates have taken effect.
